Now, on Wednesday, Hillary Clinton took aim at Trump for mixing business with politics. CNN's Chris Frates reports.

(BEGIN VIDEOTAPE)

CHRIS FRATES, CNN CORRESPONDENT: With only 12 days until the election, a new national poll shows the race tightening. And now more battleground

states are up for grabs. Hillary Clinton in a dead heat with Trump in Nevada as Trump now edges out in the must-win state of Florida.

DONALD TRUMP, (R) PRESIDENTIAL CANDIDATE: I really think that we're going to have a tremendous victory. I believe we're winning. I actually think

we're winning.

FRATES: Trump says he will invest millions more into his campaign. The billionaire so far has spent $56 million of his own money.

TRUMP: Let me just tell you that we have -- I'll have over $100 million in the campaign. FRATES: A source telling CNN that earlier this RNC Chairman

Reince

Priebus asked Trump to put more money into his campaign to help compete with Clinton's advertising blitz. The source said Trump did not listen.

HILLARY CLINTON, (D) PRESIDENTIAL CANDIDATE: Donald Trump is taking time off the campaign trail to officially open the hotel.

FRATES: Meanwhile, Clinton is blasting Trump for stepping off the campaign trail to advance his business empire.

CLINTON: Donald Trump is the poster boy for everything wrong with our economy. The facts show he has stiffed American workers, he has stiffed

American businesses.

FRATES: After opening a new hotel just blocks from the White House, the billionaire got back to campaigning with two rallies in North Carolina.

Trump hitting back at Clinton, attacking her stamina.

TRUMP: Here's a woman, she makes a speech for 15 minutes, she goes home and goes to bed. She has less energy than Jeb Bush.

FRATES: And getting upset when CNN's Dana Bash asked him about the hotel stop.

TRUMP: For you to ask me that question is actually very insulting because Hillary does one stop and then goes home and sleeps, and yet you'll ask me

that question. I think it's a very rude question, to be honest with you.

FRATES: And doubling down in an interview with ABC bringing up Clinton's attending an Adele concert in Miami.

TRUMP: Hillary Clinton goes to see an Adele concert last night and everybody says oh, wasn't that nice, isn't that wonderful. I have stopped -

- I did eight stops yesterday, three major rallies.

FRATES: Adele wasn't the only star to help Clinton ring in her 69th birthday.

(SINGING)

FRATES: Stevie Wonder serenaded Clinton on a radio show.

LU STOUT: Now, Donald Trump, he has been singing his own praises, saying that he will win this election, but can he win? And what would that take?

Now, CNN's John King maps out the state of the race.

(BEGIN VIDEOTAPE)

JOHN KING, CNN CHIEF NATIONAL CORRESPONDENT: A brand new FOX News national poll puts Hillary Clinton's lead at three points. And when you average that

out with all the other recent national polls, our CNN poll of polls shows a shrinking but still significant Clinton lead, 47 to 41 nationally over

Donald Trump as we head into the final 12 days of campaigning.

When you go the states, though, it gets more interesting when you start thinking about, can Donald Trump poll up an epic comeback?

Let's start in Florida. You look at the numbers here in the state of Florida, a new Bloomberg Politics poll out today shows Donald Trump

actually leading in Florida, 45 percent to 43 percent. That's a statistical tie. Over polls have shown Secretary Clinton with a narrow lead.

But clear Trump momentum in Florida. That's good for Donald Trump because he needs to win Florida.

The reasons why are quite interesting. If you look at why candidates get their support, if this election is about creating jobs and about changing

Washington, Donald Trump wins by a big margin. If it's about who has the right temperament to be president, who will be a role model for our

children, Hillary Clinton wins on that.

So, watch the candidates in these final 13, 12 days to try to frame to voters what this election is most about. Some other polling out at the

state level, battleground New Hampshire. It's a smaller state, a mixed verdict here.

If you look at this poll from Monmouth University, it shows a closer race, a four-point Clinton lead in that state, where she has had a big lead. But

NBC/"Wall Street Journal" also out with some new numbers that still show a nine-point Clinton lead. So, we'll keep an eye on New Hampshire, clearly a

volatile electorate, some changes as we head into the final weeks. But we leave that one advantage Clinton at the moment.

And now, let's head out west. This one here is more encouraging news for the Trump campaign, Nevada, key to both of Barack Obama's big victories.

Well, NBC News/"Wall Street Journal" poll tonight has it 43-43, a dead heat in the state of Nevada, a critical state for Trump as he tries to get to

270 and critical for Hillary Clinton as she hopes to block him.

So, let's go to the map that matters most, the race to 270. We at the moment still have Secretary Clinton winning overwhelmingly so. But what

this new data do? It makes us think about Nevada. Maybe Donald Trump can take Nevada. If he does that, he changes the map.

What about Florida? If he can hold that momentum, Donald Trump needs to win Florida. If he can do that, she is still above 270, but now, Trump is back

in play. Back in play, but still a very steep hill for the final dozen days.

Donald Trump must win North Carolina, must win Ohio. And Mike Pence out in Utah today. Mike Pence campaigning in the west. These are ruby red

Republican west states, Donald Trump doesn't have them yet. He must get them back heading into the final week.

If he gets them back, then he is in play. But even, he needs to change another one of those blue states to get there.

So, is Donald Trump in play? Are these new poll more encouraging? But is the hill still very, very steep? Absolutely.

[08:07:27] LU STOUT: Wow, that was CNN's John King there. And you can play with voting scenarios on that very same electoral map and see all the

latest news from the campaign here at CNNpolitics.com.

Now, we're getting new information on what Iraqi-led forces are facing in their push to retake Mosul. The U.S. military says that there are as many

as 5,000 ISIS fighters in the city and up to 2,000 in the defensive zone around it. Iraqi troops have now advanced within five kilometers of Mosul.

And here you see men, women, and children running from a village. Now, they are among the thousands of Iraqis who have been displaced by the

fighting.

Now, let's take you near front line outside of Mosul. Michael Holmes is there. He joins us now.

Michael, it's a week into the battle for Mosul. Where does the offensive stand now, and what's next?

MICHAEL HOLMES, CNN CORRESPONDENT: Yeah, it has been a pretty quick, a rapid advance, really, when you think about it. It has only just been over

a week since this began. Iraqi and Kurdish forces are close to Mosul, but only in certain places. To the north, the Kurds are about four kilometers

away. To the south, there is a forward unit of Iraqi intelligence which apparently -- and special forces, which apparently is within sight of

Mosul.

And there are other various units within 10, 20 kilometers or so.

There are still a lot of towns and villages to be taken -- Bashik (ph) near where we are is yet to be secured. That's about 20 kilometers away.

There's another town called Hammam al-Alil (ph). Now that is a key town. It's the last major population center from the south before Mosul. And

what's interesting there is Iraqi troops say they have surrounded it, but ISIS has apparently, according to local reports, sent in some of their most

capable fighters to be defend that place, foreign fighters, Chechens, people from Tunisia and Morocco, Afghanistan, and they are there obviously

to fight to the death.

Why defend that place and not stay within Mosul city limits? Well, perhaps to try to slow that rapid advance, do damage to men and equipment and even

perhaps morale.

It's likely to be a fierce fight. And it also diverts a lot of resources. Iraqi military having to put a lot of resources into taking out a

comparatively smaller number of ISIS enemy.

Of course, once these units all get to within range of Mosul, they will then sit, they will wait, they will coordinate before they start to go into

the city. And what they will face is a very well-prepared enemy.

We're told that dozens of suicide car and truck bombs have been pre- positioned around the city, Katusha (ph) rocket launchers as well. And then perhaps one of the most important points, something that ISIS doesn't

have to worry about and doesn't worry about, and that is civilians, perhaps a million, a million-and-a-half civilians inside of Mosul. The Iraqi

military and police are going to have to be very cognizant of that, Kristie.

[08:10:22[ LU STOUT: Yeah, absolutely. As you just reported, there with thousands of ISIS militants inside Mosul surrounding the city, foreign

fighters have been sent in, these so-called suicide squads being sent in from Raqqa. What is the coalition strategy to stop

the flow of those fighters coming in from there?

HOLMES: Yeah, that's been one of the difficulties is that that area of land west of Mosul, that is ISIS-held territory and goes all the way into

Syria. A couple days ago, we were reporting that a local tribal leader up there, a Sunni tribal leader, had seen hundreds, in his words, of ISIS

families, fighters, and even leaders heading out of Mosul and into Syria.

And then as you said then, you've got now these hundreds of suicide squad members coming in, wearing distinctive uniforms, actually wearing their

suicide belts, locals said, as they came into town, and most of them foreign fighters as well. That is the weak point at the moment.

The coalition is trying to take out verified targets from the air as they head between Mosul

and Syria. But obviously you can't just hit every moving vehicle. You don't know what's in it. Shia paramilitary are moving up that way. That

is part of their job to do some blocking from that side of Mosul, but obviously that is the weak point at the moment. And they're
